Which statement describes the endpoint of FDP?

• A. The period ends when the aircraft comes to rest and the engines are shut off.
• B. The period ends when the crew finishes their layover.
• C. The period ends when the aircraft departs again.
• D. The period ends after the first takeoff of the day.

Answer: (A)

The main idea being tested is when a Flight Duty Period (FDP) ends. The end of the FDP is the moment the aircraft is brought to a stop and the engines are shut down, signaling that active flight duties are finished and the crew can be released from duty. This point marks the boundary between the on-duty time that fatigue rules apply to and the rest that follows. It isn’t tied to a layover, a subsequent departure, or the first takeoff of the day, because those events relate to other parts of the itinerary or separate duty blocks. So the statement that best describes the endpoint is when the aircraft comes to rest and engines are shut off.
